Iphone 6+ IOS 9 error 53 problem?

I'm having a problem installing the IOS 9 to my iphone 6+ it would not install on my phone so I had to do it through itunes on my laptop. Everything looked like it was going fine but then half way through the installation it stopped and have me an error 53. I tried it again on my other laptop (mac) and still nothing it kept giving me the same error. Also when i try to turn on my phone it just gives me the itunes logo to plug it into my laptop and either update or restore I tried both & still that same "error 53" appears. I don't understand what the problem could be, I've never had to replace my screen or home button. Can someone please help me figure this out?
thanks!
